This invention relates to an elevating blackboard. In this invention, a balancing part (40) is installed in a receiving space (31) formed between an auxiliary member (30) and a wall, and blocks a balancing weight (41)'s operating part without any guide pillar, thus simplifying the overall outer shape and enhancing the product value. In addition, this blackboard is installed closely on the wall, and does not occupy much interior space. It is easy to manufacture and install such a blackboard.
